Description

Technical Field

[0001] This invention relates to the field of slag removal machine technology, and in particular to a slag removal machine scraper ash removal device. Background Technology

[0002] Ash removal machines are currently mainly used in the wet ash removal process of pulverized coal boilers in thermal power plants. Their main functions are: to maintain negative pressure in the boiler through water seals, ensuring normal boiler operation, and to transport and discharge boiler combustion products (ash and slag). As an important auxiliary machine for the boiler, the ash removal machine is placed at the bottom of the boiler. After the ash and slag fall into the bottom ash removal device of the ash removal machine, they are discharged from the end of the ash removal machine under the drive of the chain, and then loaded onto trucks for transportation, achieving continuous and efficient ash removal.

[0003] During the use of the slag remover, boiler ash and slag fall onto the bottom ash discharge device. To prevent the slag from carrying sparks and causing a fire hazard, water is usually sprayed to extinguish the fire. This increases the humidity and viscosity of the ash and slag at the bottom of the furnace, making it easy for the ash and slag to stick to the scraper and difficult to clean. As a result, more and more ash and slag accumulate on the scraper. This not only affects the transport capacity of boiler ash and slag and reduces the transport efficiency, but also accelerates the corrosion of the scraper, reduces its service life, increases the frequency of scraper replacement, and increases transportation costs, resulting in poor economic benefits.

[0026] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the drawings of the specification.

[0027] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, but the present application can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without departing from the connotation of the present application, therefore the present application is not limited by the specific embodiments disclosed below.

[0028] Secondly, the "one embodiment" or "embodiment" referred to herein means that the specific features, structures or characteristics can be included in at least one implementation of the present application. "In one embodiment" appearing in different places in the specification does not mean the same embodiment, nor is it an independent or selective embodiment that excludes other embodiments.

[0029] Embodiment 1

[0030] With reference to Figure 1 For the first embodiment of the present application, the embodiment provides a scraper ash removal device of a slag conveyor, which can realize the cleaning effect of the accumulated ash on the scraper, and comprises a slag conveying part 100, which comprises a shell 101 for bearing the products of the boiler combustion, a support 102 fixed at the bottom of the shell 101 for supporting the shell 101, a plurality of gear wheels 103 rotatably connected in the shell 101, a chain 104 engaged on the plurality of gear wheels 103, a plurality of scrapers 105 movably connected on the chain 104, and a driving assembly 106 fixed at the top of the shell 101; wherein the ash is discharged from the end of the shell 101 by using the scraper 105 under the transmission of the chain 104.

[0031] The cleaning part 200 is used for cleaning the accumulated ash on the scraper 105, which comprises a support plate 201 fixed on one side of the shell 101, a linkage assembly 202 movably connected on one side of the support plate 201, an adjusting assembly 203 movably connected on the linkage assembly 202, a limiting assembly 204 movably connected below the adjusting assembly 203, a brush 205 slidably connected on one side of the limiting assembly 204 for cleaning the scraper 105, and a knocking assembly 206 movably connected on one side of the brush 205 for knocking the brush 205 to make the brush 205 knock the scraper 105, thereby shaking off the residual ash on the scraper 105.

[0032] In summary, when the scraper 105 is accumulated with ash, the linkage assembly 202 is driven to operate by the motor 106a, and then the limiting assembly 204 is driven to move reciprocally on the support plate 201 by the adjusting assembly 203 on the linkage assembly 202, thereby driving the brush 205 on the limiting assembly 204 to move reciprocally on one side of the scraper 105 to clean the scraper 105. At the same time when the brush 205 is cleaning, the knocking assembly 206 knocks the brush 205, so that the brush 205 vibrates to drive the scraper 105 to vibrate, thereby shaking off the residual ash on the scraper 105, so that the scraper 105 is cleaned more cleanly.

[0033] Embodiment 2

[0034] With reference to Figures 2 to 4For the second embodiment of the present application, the embodiment provides a slag scraper 105 ash removal device, solves the problem that ash is adhered to the scraper, and comprises an adjusting assembly 203, the adjusting assembly 203 comprises a rotating plate 203a rotatably connected to one side of a support plate 201, a first push rod 203b fixedly connected to the rotating plate 203a, a second push rod 203c fixedly connected to the rotating plate 203a, the first push rod 203b being longer than the second push rod 203c, an adjusting plate 203d rotatably connected to one side of the support plate 201 close to one side of the rotating plate 203a, a stop rod 203e fixedly connected to the adjusting plate 203d, and a limiting block 203f fixedly connected to one side of the adjusting plate 203d.

[0035] Further, the limiting assembly 204 comprises a limiting plate 204a slidably connected to the support plate 201, a groove 204b formed in the limiting plate 204a, a fixed plate 204c fixedly connected to the support plate 201 corresponding to the groove 204b, and the limiting plate 204a being slidably connected to the fixed plate 204c in cooperation with a spring, a plurality of protruding blocks 204d fixedly connected to both sides of the limiting plate 204a, the protruding blocks 204d being triangular, the protruding blocks 204d comprising a first protruding block 204d-1 abutting one side of the limiting block 203f, a second protruding block 204d-2 on the same side as the first protruding block 204d-1, a third protruding block 204d-3, and a stop block 204e fixedly connected to the support plate 201 corresponding to one side of the third protruding block 204d-3.

[0036] Wherein, by rotating the rotating disc clockwise, the first push rod 203b and the second push rod 203c on the rotating disc are driven to rotate, when the second push rod 203c rotates to the stop rod 203e, the stop rod 203e is pushed to drive the adjusting plate 203d to pry upward from one end away from the stop rod 203e, thereby driving the limiting block 203f to disengage from the first protruding block 204d-1 on the limiting plate 204a, releasing the limiting of the limiting plate 204a, and then the limiting plate 204a slides to one side of the shell 101 by the elastic potential energy of the spring, the stop block 204e contacts the third protruding block 204d-3 to limit the sliding distance of the limiting plate 204a, when the first push rod 203b rotates to the second protruding block 204d-2, the limiting plate 204a slides away from one side of the shell 101, and the first protruding block 204d-1 presses the limiting block 203f, when the first push rod 203b is disengaged from the second protruding block 204d-2, the first protruding block 204d-1 contacts the limiting block 203f to limit the limiting plate 204a again, so that the limiting plate 204a returns to the original position.

[0037] Further, the driving assembly 106 comprises a motor 106a fixedly connected to the top of the shell 101, and a belt 106b movably connected to the output shaft of the motor 106a, one end of the belt 106b away from the motor 106a being movably connected to the gear 103.

[0038] Further, the linkage assembly 202 includes a belt two 202a movably connected to the output shaft of the motor 106a, a first bevel gear 202b rotatably connected to the end of the belt two 202a away from the motor 106a, a second bevel gear 202c fixedly connected to one side of the rotating plate 203a, and the first bevel gear 202b and the second bevel gear 202c are in meshing relationship. Wherein, the motor 106a drives the first bevel gear 202b to rotate through the belt two 202a, and then drives the second bevel gear 202c to rotate, so as to make the rotating plate 203a rotate.

[0039] In summary, when the scraper 105 is in operation, the motor 106a drives the rotating plate 203a to rotate clockwise, and then the push rod two 203c on the scraper 105 first releases the restriction on the limiting plate 204a, so that the limiting plate 204a drives the brush 205 to slide into the shell 101, thereby cleaning one side of the scraper 105 by the brush 205. When the push rod one 203b is separated from the protruding block two 204d-2, the protruding block one 204d-1 contacts the limiting block 203f to re-limit the limiting plate 204a, so that the limiting plate 204a returns to the original position and does not affect the movement of the scraper 105.

[0040] The rest of the structure is the same as that of example 1.

[0041] Example 3

[0042] Reference Figures 4 to 5 For the third embodiment of the present application, unlike the previous embodiment, the embodiment provides a scraper 105 ash removal device for a slag conveyor, which solves the problem that there is still some ash residue after the scraper 105 is cleaned once. It includes a knocking assembly 206 including a rotating shaft 206a rotatably connected to one side of the support plate 201, a plurality of fixed rods 206b fixedly connected to one side of the rotating shaft 206a, the plurality of fixed rods 206b being circumferentially distributed on the rotating shaft 206a, a sliding block 206c slidably connected to one side of the shell 101 corresponding to the rotating shaft 206a, and a push rod 206d fixedly connected to one side of the sliding block 206c, and the straight edge of the sliding block 206c is in meshing relationship with the rotating shaft 206a.

[0043] Specifically, since the plurality of fixed rods 206b on the rotating shaft 206a are in meshing relationship with the straight edge of the sliding block 206c, when the rotating shaft 206a is in meshing relationship with the upper edge of the sliding block 206c, the sliding block 206c slides away from the brush 205, and when the rotating shaft 206a is in meshing relationship with the lower edge of the sliding block 206c, the sliding block 206c slides towards the brush 205.

[0044] Further, the connecting rod 207 is fixed on one side of the rotating shaft 206a, and the belt three 208 is movably connected between the connecting rod 207 and the first bevel gear 202b, so that the rotating shaft 206a is driven to rotate synchronously with the first bevel gear 202b by the belt three 208.

[0045] In summary, the sliding block 206c reciprocatingly moves by being driven to rotate by the first bevel gear 202b, and then the push rod 206d on the sliding block 206c knocks the brush 205, and since the brush 205 is movably connected to one end of the limiting plate 204a by cooperation with the spring, when the push rod 206d knocks the brush 205, the brush 205 vibrates to drive the scraper 105 to vibrate, so that the residual ash on the scraper 105 is shaken off, and the scraper 105 is cleaned more cleanly.
